The 03749-2-4039 by ebm-papst Inc. pioneers next-generation Fans - Finger Guards, Filters & Sleeves technology for renewable energy applications. This innovative solution withstands extreme environmental conditions while maintaining optimal thermal performance. With its corrosion-resistant design, it delivers 10+ years of reliable service in solar and wind power installations.Functioning as a Finger Guard, this component provides all-weather protection with IP69K certification. Testing validates continuous operation through 1000+ thermal cycles from -40 C to 85 C with zero performance degradation.Engineered for 172mm Dia requirements in outdoor applications, this guard features a unique self-cleaning surface that reduces maintenance frequency. The hydrophobic coating maintains 95% of original airflow after 5 years of exposure.When paired with W2E142 Series, this system creates a complete environmentally-hardened thermal solution. The galvanically-isolated mounting system prevents corrosion in coastal installations.With its 5 Rings design, this solution incorporates lightning protection up to 10kA. The integrated surge protection circuitry prevents damage from electrical transients common in renewable energy systems.Constructed from UV-stabilized Metal, this guard maintains mechanical properties after 15,000 hours of accelerated weathering. Material testing shows less than 5% tensile strength loss under extreme environmental stress.
